A Taxonomy of Abstract Form Using Studies of Synesthesia and Hallucinations

The author proposes a taxonomy of abstract form anchored in an examination of the history and theory of synesthesia and abstract art. The foundations of this taxonomy lie in empirical psychological studies of "formconstants" found in cross-modal synesthetic visions and hallucinatory states, specifically the work of Heinrich Klüver in his examinations of mescaline and the mechanisms producing visual hallucinations. While the proposed taxonomy is limited only to synesthesia-inspired abstraction, it has suggestive possibilities when considered in relation to other forms of nonsynesthetic abstraction such as Islamic Art, the geometric forms found on classical Greek vases, and other kinds of decorative abstract patterns.
